  • Heel spurs (plantar fasciitis)

    Stretching or tearing of the plantar fascia, which runs along the bottom of the foot and supports the arch of the foot. A bony growth on the underside of the heel.  

  • Healthy weight

    Compared to overweight or obese, a body weight that is less likely to be linked with any weight-related health problems such as type 2 diabetes, heart disease, high blood pressure, high blood cholesterol, or others. A body mass index (BMI) of 18.5 up to 25 refers to a healthy weight, though not all individuals with…

  • Hypokinetic diseases

    Diseases caused by and/or associated with lack of physical activity. Hypokinetic diseases are lifestyle diseases resulting from inadequate physical fitness. Examples are heart disease, diabetes, osteoporosis, stroke, back pain, and cancer.  

  • Hyperthermia

    The increase in body temperature with exercise. A treatment method in which the body’s or a part of the body’s temperature is raised. General term for excessively high body temperature, as in malignant hyperthermia. Extremely high body temperature, sometimes induced as a treatment, as in some forms of cancer. Greatly increased body temperature, resulting from…

  • Hyperpnea

    Increased pulmonary ventilation that matches an increased metabolic demand, such as during exercise. An increase in the rate and amplitude of respiration. An increase in the rate of breathing that is proportional to an increase in metabolism; for example, on exercise. An increased respiratory rate, or breathing that is deeper than that usually experienced during…

  • Hydrostatic weighing

    Criterion measure for determining body composition through the calculation of body density. A method for determining body fat where the body is weighed in air and then in water. Method of estimating body fat. Also referred to as underwater weighing. A method for analyzing body composition involves measuring the amount of water displaced by an…

  • Heat stress index

    A scale used to determine the risk of heat stress from measures of ambient temperature and relative humidity.  

  • Heat stress

    The physical work and environmental components that combine to create heat load on an individual. Damage to your hair caused by using a lot of heat tools (blow-dryers, straightening irons, flat irons) consistently over a period of time.  

  • Heat strain

    The physiological responses and resulting ther-moregulatory processes to combat heat stress.  

  • Heart rate variability

    The beat-to-beat variation in the time of the R to R intervals on a standard ECG. Spontaneous fluctuations above and below the mean heart rate. A reduced HRV is associated with an increased incidence of total mortality and cardiac events in post-myocardial infarction patients, as well as in apparently healthy individuals, especially older persons.
